GOLD-SAVING- APPARATUS.

Maasai.

To all whom 15m/ay concern.'

Be it known that I, IsAAc ANDERSON, a citizen of the United States, residing at Lawndale, in the county of Los Angelesand State of California, have invented. new and useful Improvements in Gold-Saving Apparatus, of which the following is a specification.

My invention relates to apparatus for use in placer mining and the object thereof is to provide'means which will more thoroughly separa-.te and retain theJ particles of gold from the sand or pay dirt placed therein.

Another object is to provide an apparatus which 'can be used either for dry or wet washing as desired.

A further object is to provide means for preventing any particles of iron which may be in the sand from becoming mixed with the gold or amalgam.

I accomplish these objects by the apparatus described herein and illustrated in the accompanying drawingsl forming a part of this application, in which:

Figure 1 is a side elevation of mydevice lpartly in section. Fig. 2 is an end elevation of Fig. 1. Fig. 3 is a top plan of Fig. 2. Figs. d and 5 are details of the outlet.

In the drawings 5 represents the receptacle or pan supported at a suitable height by legs or other means which is formed of sheet metal, preferably copper, and slopes downwardly and inwardly in substantially the shape of a funnel. An opening 6 is formed in the center of the bottom of pan 5 around which is formed a downwardly ex tending spout An upwardly extending ridge 8 is formed in the bottom of pan 5 and surrounds opening 6. A reinforcing band or hoop 9 is secured to pan 5 Ynear the upper edge thereof to which are secured the upper ends of legs 5a. Mounted upon the top edge of pan 5 is a base plate 10 having near each end downwardly extending ears or lugs 11 and'12 integral therewith which fit against the inner sides of the pan and are held positioned by Athumb screws 13 which pass through hoop 9 and the sides of the pan. Secured to the upper side of base plate by screws 14E is a U-shaped supporting frame 15 which extends upwardly therefrom. Guide rods 16 and 17 are mounted at their lower ends in plate 10 and at their upper ends in cross bar 18 of frame 15 and extend parallel with the sides of said Specification of Letters Patent.

frame. Rollers 19 and 2,0 are mounted in bearings 2 1 and 22 vupon the upper sides and integral with base plate 10.

`paddle shaft 23 is revolubly mounted in plate 10 centrally thereof and extends upwardly therefrom and its upper end is loosely mounted in a bearing 24 integral with bar 18 of frame 15. Shaft 23 extends downwardly from plate 10 to near the bottom of spout 7 and has formed upon the lower end thereof outwardly extending projections or paddles 2,5 and 26. Secured upon shaft 23just helow plate 10 and at right angles topaddles 2 5 and 26 is a paddle 27 the ends of which extend outwardly from said shaft to near the sides of the pan. These ,paddles are substantially semi-circular in cross section. An annular elevating cam 28 is rigidly mounted upon shaft 23 by set screws or other means the lower edge of which is adapted to contact with rollers 19Vand 20. Loosely mounted upon shaft 23 and restingupon the top of cam 28 is a lower elevating bar 29 the outer ends of which are slidably mounted upon guide rods 16 and 17. A similar elevating bar 30 is mounted upon shaft 23 just below the cross bar 18 of frame 15. A Abevel gear 31 is rigidly mounted upon shaft 23 adjacent to the under side of har 30 and meshes with a similar gear 32 mounted upon operating shaft 33. Shaft 33 is rotatably mounted in a bearing 34 adjustably secured upon a U-shaped bearing frame 35 the ends of the legs of which are secured to bars 29 and 30.

An operating crank 36 is secured upon the end of shaft 33 and provides means for rotating said shaft to operate the device. Other rotating means may be provided in the place of crank 36 if desired. A magnet 37 is connected to the lower end of'spout 7 by a hinge 38, upon the top of which is secured a thin metallic plate or disk 39 and upon the top of this disk is secured a paolo ing disk 40 of fiber or other suitable material, which provides means for closing the end of spout 7 when desired and is held in a closed position by a latch 41. A sand or ore chute l2 is secured at its upper end to frame 15 and extends downwardly into pan 5 and guides the sand into said pan when the device is in use.

In operation when the device is to be used for wet panning the inner surface of pan 5 will be coated with the usual amalgam and the parts will be in the position shown in the drawings. A stream of water will be -directed into the pan. Sand or pay dirt will then be thrown upon the chute and will be guided thereby into the pan. rIhe handle will then be rotated which will cause shaft 23 to be rotated. The rotation of shaft 23 will cause cam 2S to be rotated and the lower edges thereof traveling over rollers 19 and 2O will cause shaft 23 and bars 29 and 30 together with frame 35 and its connected parts to reciprocate vertically which movement imparts a horizontal rotative and a vertical reciprocating movement to paddles 25, 26 and 27 thereby thoroughly agitating the sand and water contained in the pan. The mixed sand and water will be discharged through spout 45 in the side of the pan.

It will be understood that when the device is being operated manually one hand of the operator will be used to operate the cra-nl; and the other hand will be used to feed the sand into the chute. vWhen it is desired to use the device for dry panning latch Zll is operated to open the opening in spout 7. A supply of amalgam will be placed in the depression in the pan. rI`he handle or crank will then be operated and sand fed to the chute from which it will enter the pan and be stirred or agitated by the paddles and will pass out through the opening in the spout. Any particles of iron or iron ore in the sand will be attracted and held by the magnet 37 and'will thus be prevented from becoming mixed with the gold or amalgam.

Having described my invention what I claim is:

' 1. In a gold saving apparatus a pan having an opening in the bottom thereof, a closure for said opening, a bed plate detachably mounted upon the top of said pan, roll- Aers revolubly mounted upon said bed plate,

a U-shaped supporting frame mounted upon said bed plate near the ends thereof and extending upwardly therefrom, guide rods mounted at their lower ends in said bed plate and at their upper ends in said frame parallel with the sides thereof, a paddle shaft revolubly and slidably mounted at its upper end in said frame and near the lower end in said bed plate and extending into said pan, paddles on said shaft within thev pan, a cam on said shaft adapted to rest upon the rollers on the bed plate, a sand chute secured to said supporting frame and extending into the pan, and means to rotate said shaft.

2. In a gold saving apparatus a pan having an opening inthe bottom thereof, a closure for said opening in hinged connection therewith, a bed plate mounted upon said pan, rollers revolubly mounted upon said bed plate, a supporting frame mounted upon the ends of said bed plate, guide rods mounted between said bed plate and said supporting frame, a paddle shaft mounted to rotate in said bed plate, paddles on said shaft, a cam on said shaft adapted to contact with said rollers and move the shaft vertically when the same is rotated, and means to rotate said shaft.

In a gold saving apparatus a pan, a shaft journaled therein, paddles secured upon said shaft, and means operableby said shaft to impart a vertical reciprocating movement thereto when the same is rotated, and means to rotate lsaid shaft.

le In a gold saving apparatus a pan, a bed plate mounted upon said pan, a shaft journaled in said bed plate and extending into said pan, paddles mounted on said shaft within the pan, means mounted upon said bed plate to impart a vertical reciprocating movement to said shaft when said shaft is rotated, and means to rotate said shaft.

5. In a gold saving apparatus a pan, a bed plate mounted upon said pan, a shaft journaled in said bed plate and extending into said pan, paddles on said shaft within the pan, and means mounted on the bed plate and the shaft to impart an intermittent vertical reciprocating movement to the shaft when said shaft is rotated, and means to rotate said shaft.

6. In a gold saving apparatus a pan, a bed plate mounted upon said pan, a shaft journaled in said bed plate and extending into said pan, paddles on said shaft within the pan, means to impart one or more up andV down movements to said shaft during each rotation thereof, and means to rotate said shaft.

In witness that I claim the foregoing I have hereunto subscribed my name this 31st day of March, 1914.
